(ci. 11s- 125) This invention relates to improvementsin. liquid dispensing apparatus, and more Vespecially to novel means forblending or mixing a plurality of different liquids in desiredproportions while in the act of dispensing such liquids.

Our apparatns is particularly suitable for, although not necessarilylimited to, dispensing motor fuels and oils. With the aid of theapparatus, every llng. station can become a blending plant-blending twoo r more liquids, so as to impart any desired characteristics to theresulting liquid mixture. For example, the blending of a plurality ofgasolines, each having a different octane rating or volatility rating,or both, may be accomplished, whereby such liquids maybe combined in anydesired blend having any desired octane or volatility rating between thelimits of the octane or volatility rating of the original liquids,

The apparatus consists primarily of a means for changing the rate offlow of a plurality of liquids from two or more different sources ofsupply into a mixing box, or directly into the fuel tank of anautomobile. Various means can be supplied for accomplishing this result.For example, means of changing the rate of ow from each source can beaccomplished by a sliding system of orice devices of certain sizes togive certain desired ows; or in other words, orifices through which theliquids ilow may be variably controlled to regulate the ow of theliquids si`- multaneously through the orifices.

With the foregoing objects outlined and with other objects in view whichwill appear as the description proceeds, the invention consists in thenovel features hereinafter described in detail,

' illustrated in the accompanying drawings, and more particularlypointed out in the appende claims. i

Fig. 8 is a curve sheet illustrating the results 5 of blending gasolinesin various percentages by volume.

Referring first to Figs. 1 to 4 inclusive of the drawings, I3 designatesa pipe leading from one source of liquid, and I4 a pipe leading from a10 second source of liquid. 'I'hese pipes empty into'a mixing Abox 5having a window 6, and from the box 5 the mixture may pass through ameter 'I and valve 8 before entering the hose 8a of a dispensingapparatus. 15

If the apparatus is employed in dispensing two different kinds of motorfuels, pipe I3 will be connected to a supply of base gasoline, which maybe assumed to have an octane number vof '50, while pipe I4 will beconnected to a second 20 source of supply containing a high octanegasoline, say rated at octane number. One purposeof the invention is tobe able to form a blend of any octane number gasoline between Inaccordance with the invention, to accomplish this result, valve caslngsor devices I and 2 are interposed respectively in the pipes I3 and I4.From Fig. 3, itwill be noted that the casing I includes an oriiice orstationary port I8, while the 30 casing A2 includes an orifice orstationary port I1. 'I'hese orifices are controlled respectively bysliding plates or gate valves I6a and I6 which are suitably guided andpacked, and are actuated respectively by stems I5 and |55. Each stem has35 screw threads I5b which engage the internal threads of sockets I5cthat are fixedly attached to the sliding plates |68 and IG.

'I'he stems are geared .together by gears 3 and 4, .preferably of equaldiameter, and as these 40 gears mesh at all times, it will -beunderstood that if the knobl is turned toA rotate the stem I5, thethreads I5h will move the sliding plate I6 .in one direction, while thestem I 51% will rotate in the opposite direction and act to move the 45sliding plate I 6 in a direction .reverse to the direction of movementof the plate I6, Consequently, while one orifice is being closed, theother one is being opened.

A dial 9 is iixed to the stemv I 5B and is pro- 50 vided on its facewith concentric indicating rings .9B and 9b, etc., which cooperate witha shield II having a notch I Ia forregistration with numbers 30, 60,etc., on the rings 9 and 9b. The shield is carried by a rack Il" that isfrictionally sup- 55 ported by any suitable means, and is actuated by apawl or tooth I9 on the ,stem I 5a. Each time that stem is rotated, therack will be raised or lowered one notch, depending on the direction 5of rotation.

Each of the stems is preferably provided with a circular flange 20 thatrotates in an extension 2lix of its particular valve case, and acts toprevent axial movement of the stem. Each extension 2|)x is preferablypacked by means of a suitable packing ring 2| and an adjustable gland 22to prevent leakage along the stem.

It will be noted that the orifices I1, I8 are of the same shape,(pentagonal), but the points of the two openings are reversed. The sumof the areas of the orices is always constant for any position of theknob I0 and disk 9, or any position of the plates I6, I8, and is equalto the opening of the area I'I, which in turn is equal to the opening ofthe area I8.

While we have shown the orices of special shape, it is evident that theorifices might be made of regular shape, and the movable plates I6, I 6acould be changed in shape so that very accurate amounts of ethylizedgasoline, for example, canbe added to the mixture, at the beginning ofthe blending operation. Stated another way, one revolution of the knobI8 or the disk 9, will change the volumeiiowing through the opening I'Ia small percent at the beginning of the outward or opening movement ofthe sliding plate I6. Qne revolution of the knob I0 or the disk 9, willchange the volume to a greater extent in the last one-half of theoutward or 3,5 opening travel of the slide I6. It may, therefore,

be sen that accurate blending is obtained on the lower percent blends,(percent in terms of ethylized gasoline), which is the range where smallchanges in ratio of the two gasolines produces marked changes in octanerating.

The orifices are to be calibrated so that the disk 9 mounted on the`valve casing or device 2, will indicate the ratio of the mixtureentering the box 5, or this calibration can be calibrated in octanenumbers of the mixture.

The valve structuresl and 2 can be made so that it will requireseveralcomplete revolutions of the disk 9 or the knob I0, to completely closeor open either oriiice, and the shield II cooperating with the disk 9will properly indicate the octane number of the product, or the mixtureoi.' the same, `as the shield. will act to cover or uncover numbers suchas 30, on the various concentric circles 9, 9b, etc., corresponding toeach revolutionof '55' the disk s.

The liquids from the two sources of supply 'can thus be made to entervthe box 5 at any predetermined rate of flow, and one looking throughthe window 6 may o bserve what is taking place.

60 From the box, the mixed liquids pass through meter 'I and valve 8,and through'the hose 8Il tothe customers car. Valves 23 and 24 can beinterposed in the pipes- I3 and I4, betweenA he orice devices and themixing box-5, and these valves can be used in connection with the rvalve8, so that if the fuel tank of one car has been lled with a certainmixture oi' motor fuels,"the mixture remaining in the box 5 and meter 'Ican can be drained through the hose 8al to a sump tank, whereby when thenext customer desires a special mixture, there will be no contaminationin the equipment between the valve casings I and 2. and the nextcustomers fuel tank. 'Ihis inconvenience may be eliminated by making the75.pipes 1l3 and I4 flexible, omitting parts 5, 6, 'I

ethylized gasoline is blended with an unethylized 10 gasoline in variouspercentages by volume, typical results of the kind shown in Fig. 8 maybe obtained. From this iigure it may be seen that the 'first small blendof ethyl gasoline with the base gasoline has a much greater eiect than15 the same amount blended later; i. e., the first l5% added by volumeadds approximately 10% to the octane rating of the blended gasoline, but

15% added above 75%, adds only approximately three points to the octanerating of the blended 20 gasoline. It is evident therefore that thefirst amount of ethylized gasoline added is the most important, and doesthe most good in relation to the volume added,.than later additions ofthe same amount. 25

In Figs. 5 to 7 inclusive, we have illustrated a few adaptations of ourapparatus. For instance, Fig. 5 shows the apparatus designated forconvenience 40, installed in an existing station which has visible bowlpumps 4I and 42. The device is 3Q connected to the two pumps, as shown,with no major changes at the station. Obviouslya pair of the devicesshown in Figs. 1, 2 and 3' might be connected to the two pumps 4I and42, so that two customers may be served i'rom the two 35 pumps at thesame time, each with a dierent blend, if desired.

Fig. 6 shows the same proportioning apparatus 43 connected to two metertype pumps 44, 45,

and the remarks relative to Fig. 5 are also true o of the constructionshown in Fig. 6.

Fig. 7 shows the proportioning apparatus 46 .installed in a vendingdevice used for a new installation, as shown. The new vending device hasa motor 3Ilx driving two pumps 3|x and 32x, 45

which feed the proportioning apparatus. The characteristics of the pumps3|x and 32x should be the same so that when they are driven at exactlythe same speed, they both deliver similar streams under identicalpressures. 3|! is connected to one source of supply by the line I3, andthe other to another source of supply bythe line I4. Of course, eachsource oi.' supply will contain gasoline differing from the other.

Pumps 3|x and 32X discharge into-the pro-55 portioning apparatus 46,andthe blend travels from the latter, i'lrst through the meter 41. and

. then through the hose 8 to the fuel tank of the customers car.

It is obvious that this apparatus is of. great 60 economical importance,due to the i'act that each individual car owner can determine the ofgasoline which will best operate his car, an'd call for the same.Instead of paying a premiumI price for the total quantity placed in hiscar, it 65 will be possible to pay a premium on a percent basis,determined by himself, of the quantity lplaced in the car.

Another economic value is that two grades of gasoline will replace threeor more now being A70 handled, reducing the investment in storagetanks,pumps, etc.; Vwhile these tw grades will make available to the public aninnite number f of grades. either with respect to octane number, orvolatility, or both.

One pump 50 buy either a better grade or a poorer grade of gasoline withrespect to either the octane rating or the volatility.

While we have disclosed one embodiment of our improved apparatus and anumber of applications of the same to gasoline dispensing pumps,

it is manifest that the apparatus may be used ior the blending ofvarious other liquids, and changes may be made in the details disclosed,without departing' from the spirit of the invention, as'expressed in theclaims. .K
